MAINTENANCE Step Six
Maintenance should consist of inspection to see that the sump float is free to move and not coated with any
substance, which would change its weight or volume significantly. If this occurs, the sump float should be
cleaned. This is easily accomplished without disturbing the installation. Dents or nicks on the float are usually
of no consequence to operation.
Cleaning procedure:
1. Power: Make sure that all power to the sump float, controller and/or power supply is completely
disconnected.
2. Float removal: If necessary, make sure that the tank is drained well below the float prior to removal.
Carefully, remove the float from the installation.
3. Cleaning the float: Using a soft bristle brush and mild detergent, carefully wash the switch. Do not use
harsh abrasives such as steel wool or sandpaper, which might damage the surface of the sensor. Do
not use incompatible solvents, which may damage the sensor's PP body or PVC cable. Take particular
care to remove any scaling from the float body and make sure that it is free to move.
4. Float installation: Follow the appropriate steps of installation as outlined in the Installation section of
this manual.
